Question

Alen everage score after sixth test is 83 if Alen earns a score of 97 on the seventh test what is her new average

Answer 1

85

Explanation:

Average is calculated as

average =
`(total)/(count)`

After 6 tests

`(total)/(6)` = 83 ( multiply both sides by 6 )

total = 83 × 6 = 498

New total after test 7 = 498 + 97 = 595, hence

new average =
`(595)/(7)` = 85
